                <p> EGL&trade; is an interface between Khronos rendering
                    APIs such as OpenGL ES or OpenVG and the underlying
                    native platform window system. It handles graphics
                    context management, surface/buffer binding, and
                    rendering synchronization and enables high-performance,
                    accelerated, mixed-mode 2D and 3D rendering using other
                    Khronos APIs. </p>
                <p> The reference pages describe EGL 1.5, but can be used
                    with earlier versions since each page notes when
                    features are available only starting with specific older
                    versions (1.2, 1.3, and 1.4). </p>
                <p> A more detailed overview of EGL functionality and
                    technical concepts can be found in the <a
                    target="pagedisplay" href="eglIntro.xhtml">eglIntro</a>

                <h2>Browser Compatibility</h2>
                <p> The reference pages are now generated in HTML5 format.
                    Some pages contain imbedded MathML and rely on <a
                    href="http://www.mathjax.org/">MathJax</a> to render
                    mathematical equations on browsers which do not natively
                    support MathML. This should work much better on Chrome,
                    Safari, and other browsers which don't support MathML.
                    </p>
                <p> However, HTML5 isn't well supported on IE 8 or earlier
                    versions. We recommend you use a more recent browser for
                    viewing the reference pages. </p>

                <h2>Downloading Reference Page Sources</h2>
                <p> The Docbook source for the reference pages is available
                    in the <a
                    href="https://github.com/KhronosGroup/EGL-Registry/">
                    KhronosGroup/EGL-Registry</a> GitHub repository. You can
                    build a ref page distribution of your own using open
                    source tools. See the <a
                    href="https://github.com/KhronosGroup/OpenGL-Refpages/blob/master/README.adoc">
                    OpenGL refpage README</a> for more information on needed
                    tools. </p>
